5.1.4.5     The usedOn element on arcroleType elements
The arcroleType element MAY contain one or more usedOn elements. 
The usedOn element identifies which elements MAY use the arc role type
being defined. Standard arc elements that use the defined arc role type 
MUST be identified with a usedOn element in the arcroleType element 
whenever they appear in standard extended links.  Note that custom arc
elements are not governed by this constraint, nor are standard arc 
elements that appear in custom extended links. Within an arcroleType
element there MUST NOT be s-equal usedOn elements.
